I have a Harris RTX-2000 based system control
board for a long
defunct system. The board worked when removed more than 20 years ago
in the mid 90's. The RTX-2000 is a stack-based processor designed
for running FORTH. I think it was designed by Phil Koopman based on
his graduate work. The board is a 16-bit ISA board. It was part of
an MRI system that ran a version of MPE forth with a C-to-FORTH
compiler (actually a C-like variant) that spits out a 16-bit FORTH
variant with some embedded RTX-2000 code.
That is a bit of a surprise--in my experience it takes very little code
to support Forth on any processor--that someone would build a dedicated
chip for it is unusual.
Were there any microprocessor chips that attempted to mimic the
Burroughs B5000 series and natively execute Algol of any flavor?
